I'm thinking of retiring from Blue team and switching to Red team. Spartans are the Red team in Reach, I like Target a lot more than Walmart, and for some reason I'm getting a good feeling about Red lately.
Can you guys think of any drawbacks?

In terms of practical, in-game considerations, Blue Team is harder to see on dark maps like Derelict. Or any map on Forge World where the sky is visible (and don't even get me started on that reticle color choice). That said, we would've "won" a lot more of our ties in the early Halo 2 days if you'd come to this conclusion sooner.
In terms of the fiction, are you really comparing Red Team's Spartan IIIs to Blue Team's Spartan IIs? Ha. Not in M CHEIFS HOUSE.
I'm gonna add a poll to help you out though.

Wasn't MC on the Red Team also at some point though? I thought it was this thing where like one mission he could be on Blue, but for another he could be on Red?
You're right about Blue team on certain maps, although the blue now is more like a bright hyper blue instead of the dark blue in H2. What was the reticle color before Reach?
